libmount: export locking errors as MNT_EX_FILEIO
The mount man page assumes locking errors mapped to MNT_EX_FILEIO (16)
return code. Unfortunately, this is internally not exported as a
special error code, so it's returned as a generic (errno based)
stuff. This patch fixes this issue.
Note that we still use locking for example for utab or when enabled
/etc/mtab (disabled by default).

rfkill: allow use of multiple arguments
There is no reason why multiple arguments could not be supported.
Most common use case is to do multiple control commands in one go without us
of 'all' argument that can cause unnecessary connection breakage. For
example someone might want to add to a system initialization following
commands.
rfkill block bluetooth uwb wimax wwan gps fm nfc
That will ensure everything but wifi is turned off with as few commands as
possible, without killing wifi at any point.

The set_system_clock_timezone() function is nearly identical to
set_system_clock(). Three additional statements are required
to include systz in hctosys.
This patch is intentionally incomplete to make reviewing the
actual required changes easier. Other patches in this set will:
* remove set_system_clock_timezone()
* fix messages and debugging
* fix comments
* and finally refactor set_system_clock()

fdisk: fix readline interaction with signals
The high-level readline API is crazy to use with signals. Fortunately
the library provides low-level rl_callback_* API. In this case we can
use poll() to wait for input and control all signals, etc.
This patch also a little changes fdisk behavior on CTRL+C and CTRL+D.
The signals does not kill fdisk, but forces fdisk to return to the
main menu, if already in the main menu then exit. If the disk layout
has been modified than ask "Do you really want to exit...".

lib/randutils: improve getrandom() usage
The getrandom() does not have to return all requested bytes (missing
entropy or when interrupted by signal). The current implementation in
util-linux stupidly asks for all random data again, rather than only
for missing bytes.
The current code also does not care if we repeat our requests for
ever; that's bad.
This patch uses the same way as we already use for reading from
/dev/urandom. It means:
* repeat getrandom() for only missing bytes
* limit number of unsuccessful request (16 times)
* fallback to /dev/urandom on ENOSYS (old kernel or so...)
